For some reason it seems impossible to change the colour of a rectangle I've drawn in Photoshop after I've drawn it. I can change the colour of a new one that I want to draw but once it's drawn there doesn't seem to be any way of changing the properties of the shape. I've googled this for a while but it seems as though this is so simple there are no tutorials for it or no one knows what I mean.

Please can someone explain how to change the colour of a shape after I've drawn it in photoshop, thank you

also be sure to select the Rectangle-Tool to bring up the ribbon-menu on top of your screen so as to change not only color but also stroke-color and width or no-stroke... This can be confusing because the shape-related menu-ribbon disappears once any other tool than the shape-drawing tool is selected.

If you want to change the color of a full shape with nothing inside, a very quick trick is:

layer effects:

1) Click on the layer where your shape is

2) Double-click on that layer. A window will appear. Your layer needs to not be the background layer, by the way.

3) On this window, select the option "color overlay" and click on the little swatch of color next to the blending mode. Select the color you want!

4) You can then change the color of your shape at any time by going back in this menu. You can remove the color by unchecking the "color overlay" OR by deselecting the little eye icon on the layer, under the layer "effect" on your layer.

If you do this on a graphic that has some texture or design inside it, it will cover it all with one color though.

Hue/Saturation

Otherwise, another easy way to change a color of a shape is to go in the menu "Image", then select "adjustment", then "hue/saturation" and play around with it until you get a color you like.

Not very precise but can be interesting if you want to test how a color would look like on your shape without having to enter precise color recipe.

Thank you for your interest in this question.
